Climate Variability and Predictability Program

The Climate Variability and Predictability Program is a coordinated research initiative that advances understanding of natural and anthropogenic drivers of climate variability and the limits of predictability on seasonal to decadal timescales. It integrates observational networks, numerical modeling, and theoretical frameworks to improve forecasts used by stakeholders in sectors ranging from agriculture to energy. The program fosters collaboration among agencies, research centers, and international projects to translate scientific advances into actionable climate information.

Overview

The program emphasizes the interplay of oceanic, atmospheric, cryospheric, and biospheric processes across scales, connecting phenomena such as the El Niño–Southern Oscillation, the North Atlantic Oscillation, the Pacific Decadal Oscillation, the Madden–Julian oscillation, and teleconnections that link remote regions. It coordinates long-term observational campaigns involving platforms like the Argo float array, the TAO mooring array, and satellite missions developed by the National Aeronautics and Space Administration and European Space Agency, while aligning with modeling centers including the Geophysical Fluid Dynamics Laboratory, the Met Office, and the Max Planck Institute for Meteorology.

History and Development

Origins trace to late-20th-century efforts to synthesize knowledge from pioneers such as Charles David Keeling, Syukuro Manabe, and Jule Charney and to institutional initiatives at the National Oceanic and Atmospheric Administration, the National Science Foundation, and the World Climate Research Programme. Early milestones included coordinated experiments informed by the International Geophysical Year legacy and collaborations with programs like the Global Ocean Observing System and the International Satellite Cloud Climatology Project. Over successive phases the program expanded to incorporate paleoclimate reconstructions inspired by work at institutions like the Lamont–Doherty Earth Observatory and the Paleoclimatology Program at the National Oceanic and Atmospheric Administration.

Objectives and Research Themes

Core objectives are to quantify sources of predictability, extend lead times for skillful forecasts, and reduce uncertainties in climate projections used by policymakers and resource managers. Research themes cover coupled ocean-atmosphere dynamics exemplified by studies at the Scripps Institution of Oceanography, land–atmosphere feedbacks investigated at the Woods Hole Oceanographic Institution, cryosphere–climate interactions studied by Cold Regions Research and Engineering Laboratory, and biogeochemical cycles explored at the National Center for Atmospheric Research. Themes also include data assimilation methods advanced at the European Centre for Medium-Range Weather Forecasts and attribution science linked to work by the Intergovernmental Panel on Climate Change.

Organizational Structure and Partnerships

The program operates through a consortium model that brings together federal agencies, academic institutions, and international bodies. Key partners include the National Oceanic and Atmospheric Administration, the National Science Foundation, the National Aeronautics and Space Administration, the World Meteorological Organization, and regional research centers such as the Pacific Islands Forum Fisheries Agency and the Southern African Development Community. Participating universities include Massachusetts Institute of Technology, Princeton University, University of Washington, and University of Cambridge, with collaborative links to national laboratories like Lawrence Berkeley National Laboratory and Brookhaven National Laboratory.

Major Projects and Contributions

Notable projects have included multi-model intercomparison exercises coordinated with the Coupled Model Intercomparison Project, seasonal prediction experiments aligned with the ENSO Prediction Task Force, and decadal prediction initiatives paralleling efforts by the Climate Model Intercomparison Project. Contributions span improved seasonal forecast products used by United States Department of Agriculture planners, drought monitoring tools linked to the Famine Early Warning Systems Network, and enhanced hurricane season outlooks of interest to the Federal Emergency Management Agency. The program has supported paleoclimate syntheses that informed assessment reports by the Intergovernmental Panel on Climate Change and scenario development applied by the International Energy Agency.

Data, Models, and Methodologies

The program emphasizes interoperable data standards and open-science practices, leveraging data repositories and cyberinfrastructure such as the Earth System Grid Federation and the National Centers for Environmental Information. It advances coupled general circulation models developed at centers like the Geophysical Fluid Dynamics Laboratory and ensemble forecasting techniques used at the European Centre for Medium-Range Weather Forecasts. Methodological innovations include advanced data assimilation inspired by work at Princeton University and machine learning approaches explored at the Allen Institute for Artificial Intelligence and Carnegie Mellon University. Satellite remote sensing from Landsat and Sentinel programs complements in situ networks like Global Ocean Observing System components and paleoclimate proxies curated at institutions such as the Smithsonian Institution.

Impact and Policy Relevance

Outcomes have influenced national and international decision-making by improving climate services relied upon by agencies including the Federal Emergency Management Agency, the United States Agency for International Development, and the European Commission. Scientific advances from the program underpin adaptation planning in municipal governments, infrastructure resilience projects funded by multilateral banks like the World Bank, and sectoral risk assessments used by corporations including ExxonMobil and Ørsted. The program’s research has informed emission scenario evaluation in reports by the Intergovernmental Panel on Climate Change and contributed to capacity-building efforts coordinated with the United Nations Framework Convention on Climate Change.
